What if psychologists ruled the world? In real life?

Eat well, live longer

and look younger? Well according to the Timesnutritionist Jane Clarke you can achieve all those things by eating better.

By which she means eating less (a low calorie i.e. no more than 1,800 a day, healthy diet is claimed to add 7-10 years to your lifespan). If you are physically active however you will need more than that.

And eating foods high in anti-oxidants will reduce the cell damage caused by sun, smoke, pollution, burnt meat and rancid fat.
